        <h2>Initialization</h2>
        <p>
      <span class="emphasis"><em>size</em></span> -- number of points in the table. Must
      be a power of 2 or power-of-2 plus 1 (see <a class="link" href="f.html" title="f Statement (or Function Table Statement)"><em class="citetitle">f statement</em></a>).
    </p>
        <p>
      <span class="emphasis"><em>start, end</em></span> -- first and last value to be stored.  The points stored are uniformly spaced between these to the table size.
    </p>
        <p>
      <span class="emphasis"><em>equalpoint</em></span> -- the point on the curve when the input and output values are equal.
    </p>
        <p>
      <span class="emphasis"><em>rescale</em></span> -- if not zero the table is not rescaled
    </p>
        <p>
      The table is filled with the function x*POWER(x/eqlp,
      FL(33.0)/FL(78.0)) for x between the start and end points.  This
      is the Sone loudness curve.
